But not high flow. They allow a little better flow than the original converters, but not much more. They do sound better though. If I can get true duals on my car, they may work even better and the y pipe may be the main issue I'm having. Installation was a cake walk. Getting the old ones off was a pain, but these went on very easily. Would have been better if they matched up to the OE air injection without modification, but that's not a big deal.

I wanted something that would be deep and a little louder my silverado but not wake up my neighbors loud. If you are looking for something like my first sentence said this is it. There is a little drone in the cab but you can turn your volume on your stereo up just a bit and it drowns it out. It has the perfect deep tone I wanted and the exact amount of loud I want as well. Great product!!!
